Genesis 34:17-27

17 But if you will not listen to us and be circumcised, then we will take our daughter and be gone."
18 Their words pleased Hamor and Hamor's son Shechem.
19 And the young man did not delay to do the thing, because he was delighted with Jacob's daughter. Now he was the most honored of all his family.
20 So Hamor and his son Shechem came to the gate of their city and spoke to the men of their city, saying,
21 "These people are friendly with us; let them live in the land and trade in it, for the land is large enough for them; let us take their daughters in marriage, and let us give them our daughters.
22 Only on this condition will they agree to live among us, to become one people: that every male among us be circumcised as they are circumcised.
23 Will not their livestock, their property, and all their animals be ours? Only let us agree with them, and they will live among us."
24 And all who went out of the city gate heeded Hamor and his son Shechem; and every male was circumcised, all who went out of the gate of his city.
25 On the third day, when they were still in pain, two of the sons of Jacob, Simeon and Levi, Dinah's brothers, took their swords and came against the city unawares, and killed all the males.
26 They killed Hamor and his son Shechem with the sword, and took Dinah out of Shechem's house, and went away.
27 And the other sons of Jacob came upon the slain, and plundered the city, because their sister had been defiled.
